Court documents reveal an investigation going back to mid June, when police and troopers first contacted Milligrock through what Nome Police Chief John Papasodora called “undercover purchases” of drugs, including heroin. Arresting documents state Milligrock “handed [police] a vial” containing a small amount of meth, leading investigators to follow up with a search warrant for his East 5th Avenue home.

In the search, police and troopers say they found five vials of heroin and “a small bag” of crystal meth. Court records, however, show Milligrock wasn’t arrested after the June search of his home—but that wasn’t the end of the investigation, which eventually led to what police and troopers say was Milligrock’s “drug stash” found “off of an ATV trail within the city limits of Nome.”

An affidavit from a Nome police officer states the stash held more than 21 grams of heroin, with each gram “packaged for sale.” The stash also held a clear glass vial filled with 1.2 grams of meth, or roughly five doses on the street.

Chief Papasodora wrote in a Thursday email the 21 grams of heroin could be sold on the street as more more than 200 individual doses of the drug.

“It’s a lot, and especially a lot for a community the size of Nome,” said Captain Jeff Laughlin, the commander of the trooper’s Statewide Drug Enforcement unit.

“If you associate a gram, you know kind of the size of a sugar packet, right? So, the last pricing I got that’s pretty accurate for western Alaska is, generally a gram [of heroin] is going for about $1,000. So, approximately $22,000 worth for [approximately] 22 grams.” Laughlin added the heroin would likely be sold one-tenth of a gram at a time, for about $100 each.

Investigators interviewing Milligrock wrote in papers submitted to the court that he admitted the drugs belonged to him, and allege Milligrock confessed to officers that “he sells heroin in Nome.”

In all he faces seven felony counts for misuse of a controlled substance, including two second-degree charges.

In his first court appearance Thursday, to formally hear the charges against him, Milligrock requested a court-appointed attorney and pleaded not guilty to all charges. Bail was set at $15,000. Milligrock remains in custody at Nome’s Anvil Mountain Correctional Center.

The Nome Police K9 unit with K9 “Icon” was cited by Chief Papasodora as “an instrumental part in the seizure.” Nome’s only K9 officer died unexpectedly last month while undergoing emergency surgery. Chief Papasodora didn’t provide specifics of the K9 unit’s involvement in Milligrock’s but wrote simply that “we will really miss Icon.”

Milligrock’s criminal history includes three separate felony convictions in 1996 on felony burglary, theft, and criminal mischief charges in Nome, and one felony conviction for escape in Anchorage.
